Five-Domain Breakdown
The CDI is an equal-weight composite of five family-v1 distress domains. Each domain contributes 20% of the county score.
Methodology
The County Distress Index scores household financial distress from 0 to 100 for all 3,144 U.S. counties. A county's score is the share of U.S. counties it is more distressed than. The index is built from five equal-weighted domains: Delinquency, Default & Legal, Debt Burden, Labor, and Safety Net & Buffer. Each domain is the mean of distress-oriented indicator percentiles; the five domains are averaged, and that average is ranked against every other county to give the score.
Data sources include the Urban Institute Debt in America (Equifax consumer credit panel), Equifax data retrieved via FRED (subprime credit share), U.S. Census Bureau (American Community Survey 5-year, Small Area Income and Poverty Estimates), U.S. Bureau of Labor Statistics (Local Area Unemployment Statistics), Administrative Office of the U.S. Courts (F-5A bankruptcy filings), and U.S. Department of Housing and Urban Development Fair Market Rents. Data vintages range from 2024 to 2027 depending on source; full indicator-level vintage detail is in the methodology document.
